    Answer:

    Mean = 48.5, Median = 53, Mode = nothing, Outlier = 17

    Step-by-step explanation:

    Mean: Add all the numbers (388) then divide by how many numbers (8) are there. (= 48.5)

    Median: Is the middle number () so you have to order them from least to greatest (17, 42, 45, 52, 54, 57, 58, 63) and then just keep marking them off left, right, left, right… until you get to the middle. But since there are two numbers (52, 54) you have to add them (106) then you divide by 2 (53).

    Mode: Is the number that shows up the most. In this case none of them do.

    Outlier: The number that is farthest from the other numbers (17).
